Lyndon et al.,

Continuing with Pittsburgh streetcar line traffic data from 1948 (Part 3):

23 - Sewickley
13.6 miles
3,291,000 revenue passengers

25 - Island Avenue, 26 - West Park, 34 - Elliott (combined)
4,789,000 revenue passengers

27 - Carnegie
7.3 miles
1,903,000 revenue passengers

28 - Heidelberg
8.1 miles
2,318,000 revenue passengers

30 - Crafton-Ingram, 31 - Sheraden-Ingram (combined)
10.2 miles
3,354,000 revenue passengers

West End lines (combined)
26.5 miles system length (unduplicated).
15,655,000 revenue passengers.

20.8 million "total passengers" (above figure multiplied by 1.33.)

Composite ATD: 2 miles. Determined by assigning average travel
distance per revenue 
passenger to the lines - arbitrarily - as follows:

23 - Sewickley: 3 miles.
25 - 26 - 34: 2.5 miles.
27 - Carnegie: 2.5 miles.
28 - Heidelberg: 2.5 miles.
30 - 31 Crafton: 2.5 miles.

I then calculated a "weighted average" travel distance per revenue
passenger, 2.6 miles. 
This, adjusted "downward" to account for revenue and transfer
passengers, gives 2.0 miles 
ATD. (As before, this figure is presented on the "traffic density
tables" as simply "2 mi.")

("Depopulation" is also visible in the West End region. Some areas,
notably parts of the 
Corliss - Ingram - Crafton circular, have very few residences
remaining along the former 
streetcar lines.)
